JAKARTA (Reuters) - Indonesian President Joko Widodo replaced the social affairs minister in his Cabinet on Wednesday and picked a new chief of staff in the third reshuffle of his five-year term.

The reshuffle was widely expected because some of Widodo's ministers have requested leaves of absence to stand in regional elections later this year.

However, with only one minister involved, it was more modest than some expectations.

The new social affairs minister is Idrus Marham, a member of Golkar, the second-largest party in Widodo's coalition. He replaces Khofifah Indar Parawansa, who is standing for election in East Java province.
